Prediction and control of symmetry breaking in embryoid bodies by environment and signal integration
Transplantable mouse teratomas are known to contain multipotential teratocarcinoma stem cells analogous to early embryo cells and capable of giving rise to a wide variety of specialized cell types in vivo when they attach to a substratum; if they are grown instead in suspension in the body cavity, they form multicellular embryoid bodies which proliferate with little or no cell specialization. T...
introduction: to evaluate the camp -mediated ibmx (3-isobutyle -1-methyl xanthin) and db-camp (dibutyryl camp) effects on differentiation of human embryonic stem cells (hescs) into nerve cells were the objectives of this study. methods: we have used royan h1 hesc- derived embryoid bodies with four treatment groups: six days treatment with ibmx (5×10 -4m) and db-camp (10 -9m) (referred to as cam...
OBJECTIVE The purpose of this study was to clarify the role of fibroblast growth factors (FGFs) and FGF receptors (FGFRs) in hematopoietic/endothelial development. METHODS AND RESULTS Using several different FGFR-1-specific antibodies and FGFR-1 promoter-driven LacZ activity, we show that FGFR-1 is expressed and active as a tyrosine kinase in a subpopulation of endothelial cells (approximatel...
Fetal alcohol spectrum disorder is a collective term representing fetal abnormalities associated with maternal alcohol consumption. Prenatal alcohol exposure and related anomalies are well characterized, but the molecular mechanism behind this phenomenon is not well characterized. In this present study, our aim is to profile important genes that regulate cellular development during fetal develo...
